<h2>Answer :</h2>
A wheel is a circle.
Given diameter of wheel = 2.8 m
Then radius of the wheel = 2.8/2 = 1.4 m
Now we know that , circumference of circle =![2\pi r](https://tex.z-dn.net/?f=2%5Cpi%20r)
<h3>Then, </h3>
Circumference of wheel = 2 × 22/7 × 1.4
Circumference of wheel = 8.8 m
<u>From the above we can conclude that ;</u>
1 revolution = 8.8 m
x revolution = 484 km = 484000 m
<h3>Thus, </h3>
![x = \frac{1}{8.8} \times 484000 \\ \\ x = 55000](https://tex.z-dn.net/?f=x%20%3D%20%20%5Cfrac%7B1%7D%7B8.8%7D%20%20%5Ctimes%20484000%20%5C%5C%20%20%5C%5C%20x%20%3D%2055000)
<h3>Therefore, total of 55,000 revolutions are made by the wheel.</h3>
Answer:
So 0.71 and 54 represent the same level of precision.
Step-by-step explanation:
Precision is how many significant figures have been measured. This is the number of digits in between the first and last non-zero digit.
In this case what we have:
1265.12 = 6 sig figs
0.71 = 2 sig figs
24.5 = 3 sig figs
54 = 2 sig figs
So 0.71 and 54 represent the same level of precision.
This is answer of your question and i hope you get the idea.
Sorry. Had to redo this with the correct answer.
Here it is...
Solve for x by simplifying both sides of the equation, then isolating the variable.
Exact Form:
x = - 2/5 (fraction)
Decimal Form:
x = - 0.4 (decimal)
Solve what? (ugh why is there a least amount of character limit)
For this you do Pythagorean theorem so
7^2+12^2=x^2
49+144=x^2
193=x^2
x=squareroot193
so you put 193 in the green box.
hope this helped❤️
